Abstract: Disclosed is an apparatus for using negative pressure energy of an engine, comprising: a first cavity (10), which first cavity (10) is in communication with the atmosphere via a first intake port (20); a second cavity (30), which second cavity (30) is in communication with the intake port of the engine (50) for supplying air to the intake port of the engine; a second intake port (40), which second intake port (40) is connected to the second cavity (30), wherein when the second intake port (40) is open, the second cavity (30) is in communication with the atmosphere for supplying the air to the intake port of the engine; and a rotating device (60), which rotating device (60) is located between the first cavity (10) and the second cavity (30), and can be rotated under the action of pressure difference between the first cavity (10) and the second cavity (30). Further disclosed is a method for using negative pressure energy of an engine.

Abstract: A detachable steering mechanism, comprising a steering wheel (1), an upper steering column (2), a worm (10), and a drive system and control system (20); said steering wheel (1) being fixedly connected to said upper steering column (2); said upper steering column (2) being provided with a thread (11), and a first drive gear (3) being provided on said worm (10); the thread (11) of the upper steering column (2) meshing and rotating with said first drive gear (3); upon said control system (20) detecting the ejection of the steering wheel airbag, controlling said drive system to drive said worm (10), said first drive gear (3) is driven to move away from the thread (11) of the upper steering column (2), allowing said upper steering column (2) to move along its own axis.

Abstract: An electric vehicle driving system includes an energy-storage apparatus (1), a first motor (2), a speed regulating motor (3) and a single row planetary mechanism. Said first motor (2) and said speed regulating motor (3) are connected electrically to the energy-storage apparatus (1). The single row planetary mechanism includes a sun gear (4), a gear ring (5) and a planetary carries (6) with planetary gears (7). The planetary gears (7) in the planetary carrier (6) mesh the gear ring (5) and the sun gear (4) separately. The output axle of the first motor (2) is connected to the gear ring (5), and the output axle of the speed regulating motor (3) is connected to the sun gear (4) by a brake (8). The invention takes the speed regulating motor and the single row planetary mechanism instead of the gearbox in a transmission driving system, and achieves a simple and compact structure, easy assemble, light weight, and low manufacturing cost.

Abstract: Disclosed is a hybrid propulsion system, comprising an engine, a first motor, a second motor, a power coupling device and a drive shaft. The power coupling device includes a first propeller shaft connected with said engine via a first clutch, a second propeller shaft connected with the rotor of said first motor, and a third propeller shaft connected with the rotor of said second motor. By a planetary gear mechanism with an inner ring gear, said first propeller shaft, said second propeller shaft and said third propeller shaft come into driving engagement with one another. Said inner ring gear and said third propeller shaft are individually selectively in driving engagement with said drive shaft.
